Components 1 to 10 can be selected according to your specific needs. For example, you can choose whether to include glass windows or soundproof doors. The soundproof panels can be selected as either removable or fixed. This offers great flexibility, allowing us to customize products that are suitable for your project according to your requirements.
Using corner joiners, a right angle can be formed on straight barrier walls to create open acoustic enclosures / shields.
Using acoustic roof panels and access doors, complete enclosures can be made to reduce sound from machinery or isolate staff working in noisy industrial environments.
Vibration Isolation
Where structurally transmitted noise and / or vibration must be controlled, acoustic enclosures are built upon a floating floor system on vibration isolators.
The isolators used can be tailored to suit individual project requirements.
Ventilation systems can be provided for acoustic enclosures of both personnel and industrial machinery.
Application
| Industrial Manufacturing: | Used to soundproof machines, compressors, generators, and other noise sources to reduce noise levels in the workplace. |
| Construction Sites | Employed to mitigate noise from construction equipment (such as concrete mixers and excavators), minimizing the impact on surrounding residents or other construction sites. |
| Transportation Facilities: | Applied around railways, airports, and highways to reduce traffic noise affecting the surrounding environment. |
| Commercial Spaces | Used in public areas like shopping malls, restaurants, and cinemas to enhance customer comfort and privacy. |
| Laboratories and Research Institutions: | Utilized in acoustic laboratories and testing rooms to ensure the accuracy of experimental data by minimizing external noise interference. |
| Residential Areas: | Implemented in neighborhoods to isolate noise between homes, improving living comfort. |
| Healthcare Facilities: | In hospitals, soundproof enclosures can reduce equipment noise, creating a quieter treatment environment. |
| Music and Recording Studios: | Used in audio recording and music production spaces to prevent external noise from affecting sound quality. |

Acoustic Door and Louver Door
We have two different series of soundproof doors to meet various noise reduction requirements. For closed spaces where ventilation and pressure loss are not a concern, we can provide professional soundproof doors to fulfill the needs. For situations like equipment rooms or engine rooms, where indoor air circulation and heat dissipation are important, we can provide soundproof louver doors. These louver doors can meet noise reduction requirements while also allowing for proper ventilation and heat dissipation
